GCN Circular 12108
A. von Kienlin (MPE) reports on behalf of the Fermi GBM Team: "At 03:37:11.94 UT on 05 July 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110705A (trigger 331529833 / 110705151). The on-ground calculated location, using the GBM trigger data, is RA = 160.6, DEC = +24.0 (J2000 degrees, equivalent to 10h 42m, 24d 0'), with an uncertainty of 4.7 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 75 degrees. This burst was also independently detected by INTEGRAL SPI-ACS. The GBM light curve consists of one short spike with a duration (T90) of about 0.2 s (50-300 keV). The time-averaged spectrum from T0-0.016 s to T0+0.208 s is best fit by a Band function with Epeak = 1010 +90/-80 keV, alpha = -0.17 +/- 0.07, and beta = -3.0 +0.2/-0.4. The event fluence (10-1000 keV) in this time interval is (3.3 +/- 0.1)E-06 erg/cm^2. The 0.016-sec peak photon flux measured starting from T0+0.0 s in the 10-1000 keV band is 50 +/- 4 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
